DETAILED DESCRIPTION OF THE INVENTION

From time-to-time, the present invention is described herein in terms of these example environments. Description in terms of these environments is provided to allow the various features and embodiments of the invention to be portrayed in the context of an exemplary application. After reading this description, it will become apparent to one of ordinary skill in the art how the invention can be implemented in different and alternative environments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as is commonly understood by one of ordinary skill in the art to which this invention belongs. All patents, applications, published applications and other publications referred to herein are incorporated by reference in their entirety. If a definition set forth in this section is contrary to or otherwise inconsistent with a definition set forth in applications, published applications and other publications that are herein incorporated by reference, the definition set forth in this document prevails over the definition that is incorporated herein by reference.

The following discussion is presented to enable a person skilled in the art to make and use the invention. The general principles described herein may be applied to embodiments and applications other than those detailed below without departing from the spirit and scope of the present invention as defined by the appended claims. The present invention is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.

The invention is directed toward a labeled cable and an apparatus for affixing a label to a moving cable, and more particularly some embodiments are directed to a labeled corrugated cable and apparatuses and methods of applying a label to the cable.

Referring now to FIG. 1 , an exemplary cable or conduit in accordance with one embodiment of the invention is disclosed. A smooth, attachable, printable label 1 is affixed to the sheath of a corrugated cable 2. The label has a label body 1A or substrate that bridges across the grooves 4 adjacent to and alternating between the ridges 3 of the sheath of the cable. The body of the label 1A may wrap around the cable less than or equal to 360 degrees. In another disclosed embodiment, the body of the label 1A may wrap around the cable more than 360 degrees for retention to the cable 2. The label body 1A may have an adhesive on the side of the label 1 that attaches to the cable 2 and may be of a thickness that prevents the label 1 from dipping down into the grooves 4 of the cable 2 when it is attached to the cable 2. In another disclosed embodiment, the label 1 attaches to the cable 2 by dipping down into the grooves 4 of the cable 2 and at least partially conforming to the ridges 3 and grooves 4 of the cable 2. The adhesion of the label 1 to the ridges 3 permits the label 1 to conform to the circumference of the sheath and stay attached to the ridges 3 of the cable 2. In one disclosed embodiment, the thickness of the label is between 1.5 to 2.0 mil. When the body of the label 1A is wrapped around the cable more than 360 degrees, it will overlap itself and adhere to part of itself, which provides more adherence and longevity of its life and purpose which, in one embodiment, is to display information regarding the cable, however any type of information may be displayed. The body of the label 1A after it is attached to the sheath of the cable 2, provides a continuous surface with a relatively flat configuration that may serve as a canvass to paint on or print on. In another disclosed embodiment, the label body 1A may be emblazoned with human and/or machine readable data. The human and/or machine readable data includes alpha numeric characters which may display manufacturer specific information, cable specifications, warnings, advertisement, or job-site designations. The purpose of the alpha numeric characters includes identifying the number of conductors, type of insulation, type of cable, type of application, or anything at all including but not limited to the wire gauge. Further, as is disclosed in FIG. 2 , the electrical characteristics of the cable 2, the 120 V indicia on the label body 1A, may be provided.

In one embodiment, the label 1 may be comprised of electrically conductive material such as electrically conductive polyofelin and may include an electrically nonconductive adhesive.

Referring to FIG. 2 , a diagram of a perspective view of a labeled cable in accordance with one embodiment of the invention is disclosed. To indicate that the cable 2 is of the particular type, a label 1 is affixed around the circumference of the outer surface of the sheath of the cable 2. In one disclosed embodiment, the label 1 has writing 1B on it to coincide with the insulations and to indicate the type of the conductor inside the MC or AC cable, thus relieving the person looking for information pertinent to the cable 2 from having to have knowledge in deciphering a code for cables, that may for example include colors, dots, dashes, stripes, bands, solid colors, and any other patterns and indicia requiring a particular knowledge, for cables, in order to quickly obtain information regarding the cable 2.

In one disclosed implementation of the invention shown in FIG. 2 , an MC or AC type 277-volt flexible armored cable 2 includes several internal conductors and a readable label 1 affixed and displayed on the outer surface of the sheath that is emblazoned with letters of any alphabet 1B. In this implementation, there is no need to print information on the cable 2 itself, as the label 1 provides the substrate for printing. Persons who install or maintain a labeled cable in accordance with a disclosed embodiment of the invention, may quickly and instantly read the label 1 to identify the conductors in the particular type of cable 2, such as their gauge, voltage rating, etc., even though they may not be able to see the insulation on the internal wires. They may also recognize the cable 2 as being of type MC or AC based on the writing on the label 1. Knowing the type or function of a given cable 2 without seeing the insulations on the internal wires, and without having to memorize a code, can save time and reduce hazards.

A sequence of labels can be repeated all along the length of the cable. In one disclosed embodiment, labels 1 may be placed on successive sections of a steel or metal cable 2 as it is dispensed from a feed roll and just before the strip enters a forming machine where it is convoluted.

In the case of a labeling machine that applies the label to a moving steel strip just before it enters the forming (convoluting) machine, the labeling machine must be able to switch labels quickly and to apply and cure or shrink the label in a short time between when the strip arrives at the labeling machine and when it is delivered into the forming machine.

The labels 1 may be a tag or sticker, for identifying a continuous processed cable, wire, conductor, hose, tube, rod, belt, cord of round, oval, rectangular or other cross sectional shape, that is attached to the outside surface at certain intervals and are emblazoned with human and/or machine readable markings or indicia.

In one disclosed embodiment, the label body 1A may be composed of polyolefin and have a thickness from 1.5 mil to 2.0 mil. However, the label body 1A may be any other shrinkable or non-shrinkable material, or polyester or other plastic or elastomer or paper or a thin, film type metal or natural, organic or inorganic substance or material that will conform to the shape of the cable, wire, conductor, hose, tube, rod, belt, cord of any cross sectional shape.

Referring now to FIG. 2A, a diagram of a roller 225 forming part of an apparatus for affixing labels to a moving cable in accordance with one embodiment of the invention is disclosed. In another disclosed embodiment, the label body may wrap around the cable less than 360 degrees around the outer surface of a continuous processed, cable, wire, conductor, hose, tube, rod, belt, cord of any cross sectional shape.

In a further embodiment, the label 1 does not attach continuously along the length of said cable, wire, conductor, hose, tube, rod, belt, or cord 2 of a particular cross sectional shape but is attached at certain, repeated, determinable intervals and thus requires the tag or label 1, to be of certain length along the cable, wire, conductor, hose, tube, rod, belt, or cord 2 of said cross sectional shape.

In one disclosed implementation, affixing a label 1 to a cable 2 is achieved by attaching the label 1 onto the cable 2 after the cable has been helically wrapped with metal sheathing such as with armored cable or metal-clad cable.

Referring to FIG. 2B, a diagram of a roller and a label with holes disposed thereon attached to the cable in accordance with one embodiment of the invention is disclosed. In this disclosed embodiment, the label 1 has holes 10, or perforations, disposed throughout label 1 that penetrate completely through the label 1. When the label 1 is placed on the cable 2, the holes 10 serve to prevent the label 2 from impeding the flow of electrical current. For example, if the cable 2 is feeding into an electrical junction box, it is often desirable to ground the cable 2 via electrical contact with the junction box. If the point of contact between the cable and the junction box happens to line up with a labeled portion of the cable 2, the holes 10 allow for electrical contact between the labeled portion of the cable 2 and the junction box.

FIGS. 3-10A depict one disclosed embodiment of an apparatus for affixing one or more labels to a cable moving in line with the cable's axis. The labels 1 have front and back sides and a perimeter. Referring to FIG. 3 , the apparatus includes a label dispenser having a speed of dispensing labels that is adjustable and synchronized with the linear speed of the moving cable 2. A bottom push up roller 220 is separated by a distance D from an edge 307 of a peel blade 305 of the dispenser. The distance D is determined based on the stiffness of a label as it detaches from its backing strip. The distance D will necessarily be less than the length of a label 1. The labels 1 dispense with the adhesive side facing up as shown in FIG. 5 . In one disclosed implementation, the dispenser and the peel blade 305 are positioned to dispense and peel labels 1 in the same direction as the motion of the cable 2 moving along its axis.

In one disclosed embodiment, the cable 2 may be positioned to move over the peel blade 305 at a point 309 along the edge 307 so that the label forms an unequal U shape around the cable when received by the bottom push up roller 220. Referring to FIG. 4A and FIGS. 5-11 , depending on the point 309 where the cable 2 moves over the labels 1 moving off the peel blade is positioned, the disparity 242 in height of the sides 241, 243 of the label as it is formed into a U shape may be adjusted. For example, if the cable 2 is centered on the labels 1, the sides 241, 243 of the sides of the U shape label will be equal in height. As the cable is positioned further from a center line of the labels 1, the more unequal the heights of the sides 241, 243 will be when folded up into the U shape.

Referring to FIGS. 5 and 12 , the bottom push up roller 220 has a channel 230 configured for receiving a cable 2 to be labeled, and the channel 230 is bounded by side walls 225. The roller 220 is configured for folding a label into a U shape around the cable 2 as the cable 2 and label 1 enter the roller 220. The roller 220 is rotatable about its axis 235 and the axis 235 is perpendicular to the direction of travel of the cable 2. The bottom push up roller 220 is disposed below the moving cable 2 so the cable 2 moves between the side walls 225. The side walls may assist in affixing the adhesive backed label 1 to the cable 2.

Referring to FIGS. 7-9 , downstream of the bottom push up roller 220 is a first roll down roller 310A. The first roll down roller 310A is disposed lateral to a first side 2A of the moving cable 2 and has a channel 230 bounded by side walls 225 and is configured to receive a moving cable 2 having a label 1 partially folded over therewith into a U shape by the bottom push up roller 220. The first roll down roller 310A is configured to fold down a shorter side 241 of the label 1 onto the moving cable 2.

In another disclosed embodiment, the roll down rollers 310A, 310B may only have one side wall for folding down the sides of the U shaped label on the cable 2.

Referring to FIGS. 8 and 9 , further downstream is a second roll down roller 310B disposed lateral to a second side of the cable, opposite to the first side, and has a channel 230 bounded by side walls 225. The second roll down roller 310B is configured to receive a moving cable 2 having one shorter side 241 of the label folded down onto the cable 2 by the first roll down roller 310A. The second roll down roller 310B is configured to fold down a longer side 243 of the label 1 onto the moving cable 2 and over the shorter folded down side, with part of the adhesive side of the label 1 affixing to the top of the shorter folded down side.

Referring to FIGS. 10 and 11 , downstream of the roll down rollers 310A, 310B is a top push down roller 265. In one disclosed embodiment, the top push down roller 265 is solid with no channel and presses the label 1 against the cable 2 to secure attachment. In another embodiment, the top push down roller may be of similar shape to the bottom push up roller 220 and include a channel and side walls for receiving the cable 2.

In another disclosed embodiment, illustrated in FIG. 11 , a heat tunnel 231 may be provided downstream of the rollers. After the label 1 is affixed, the labeled cable 2 may be treated with hot air or radiant heat to cause the label 1 to shrink, preferably circumferentially. The heat tunnel and all the other components of the apparatus for affixing labels 1 to the cable 2 may be configured to rise out of the way when a scrambled or broken cable 2 approaches the apparatus.

In operation, an unlabeled cable 2 moves in a direction in line with its axis as indicated by the thick arrows in the figures. A label dispenser dispenses labels 1 adhered to a backing strip. As the backing strip moves over a peel blade, a label 1 detaches from the backing strip and is caught by the bottom push up roller 220 and is wedged between the cable and the roller 220. As the roller rotates, the label 1 is folded upward over the sides of the cable 2 so that two sides of the label are upright in a U shape. Next, the folded label 1 moves with the cable 2 into the first roll down roller and one side of the label is folded down. Subsequently, the cable 2 with the label 1 having one side folded down enters the second roll down roller 310B and a side wall pushes down the other side of the label 1. Subsequently, the labeled cable 2 is moved under the top push down roller to further press the label against the cable 2.

In another disclosed embodiment, shown in FIG. 13 and FIGS. 13A through FIG. 13J, the dispenser and peel blade 305 is oriented to dispense labels 1 perpendicular to the direction of motion of a cable 2 moving along its axis. Referring to FIG. 14 , a tamp pad 205 is provided having a U shaped channel 215 disposed in a flat top side 212 of the tamp pad 205. Vacuum ports 214 are disposed on the top side 212 to receive labels having an adhesive side facing up dispensed from the peel blade 305. The tamp pad having received a label 1, moves upward to engage a moving cable 2 into the channel 215, thus folding the label 1 into a U shape in the channel between the tamp pad 205 and the moving cable 2 as depicted in FIGS. 13B through 13D. Depending on the distance between the tamp pad 205 and the peel blade 307, the sides of the label 1 folded in to a U shape will be of differing heights.

Since the cable 2 is moving, the label 1 has traveled off of the tamp pad 205 and the grooved tamp pad returns to a lowered position away from the moving cable 2 and another adhesive backed label 1 may be dispensed onto the tamp pad 205. Vacuum holes 214 in the grooved tamp pad in the flat area of the grooved tamp pad are commencing with a vacuum condition to hold the label 1 in place for a specified period of time until the grooved tamp pad is pressed against the moving cable 2 and another U shaped attachment configuration cycle is repeated.

The labeled cable may then move into a bottom push up roller 220 for further securing the label to the cable. Next, the folded label moves with the cable into the first roll down roller and the shorter side of the label is folded down. Subsequently, the cable with the label having the shorter side folded down enters the second roll down roller 310B and a side wall pushes down the other taller side of the label. Subsequently, the labeled cable is moved under the top push down roller to further press the label against the cable.

In yet another disclosed embodiment, as shown in FIG. 13G1, a second tamp having a channel configured to press down a shorter side of a U shaped label 1 is disclosed. Downstream, a third tamp pad may press down the other taller side of the label 1. The second and third tamp pads may be used in place of the roll down rollers 310A, 310B, but otherwise, the components in the above described embodiments may remain the same.

A heat tunnel with a specified opening and a specified length and a specified wattage for heat generation encompasses the moving labeled cable 2 downstream of the rollers. When the When the moving labeled cable 2 enters the heat tunnel, the heat is controlled specifically for shrinking the label 1 in a specified way without damaging the text on the label 1. Independent of how large and bold any text displayed on the label 1 is, the label 1 will not absorb too much heat to damage the label 1. The heat is controllable for different sizes of labeled cable 2.

A release system with a specified range of opening causes the labeling and wrapping mechanisms to part or move away from the moving cable 2. This is to eliminate damage to the labeling and wrapping mechanisms when damaged, frayed, stringy, etc. sections of cable arrive at the labeling wrapping mechanism.
